ROTARY BRUSH.

Specification of Letters Patent.

Application filed October 20, 1915. Serial No. 56,9116.

T0 all whom 'it may concern Be it known that I, RALPH B. GooD'RIoH acitizen of the United States,Av residing atA College Hill, lin thecounty of Hamilton and State 'of Ohio, have invented certain new and'useful Improvements in Rotary Brushes, of which the following is aspeci'- fication.

This invention relates to a novel improvement in brushing-and scrubbingdevices of the type which employ a rotary brush, and which-areparticularly adapted for washing automobiles or other vehicles, althoughsusceptible to a wide rangevof other uses.

To this end, the invention contemplates a simple and practical devicewhich utilizes a supply of running water for the two-fold f purpose ofrotating the brush element, and

also supplying thereto the necessary water for the washing operation.That is to say, the invention has in- Iview a novel construction wherebythe same water which actuates the brush-operating instrumentalities, isfed to the brush without waste or leakage, thereby providing a device ofthis character that not only economizes the consumption of water butgives a maximum cleaning eiiciency for the water used in a safe andconvement manner.'

Another object of the invention 1s to provide a novel brush operatingdevice that 1s easily made 'and assembled, and capable of bei-ng readilytaken apart to facilitate repairs and renewals. invention proposes toutilize a special brush which constitutes an essential part of theapparatus, and may be easily and quickly connected or disconnected fromthe brush4 operatingv deviceA when desired, but when coupled therewith,is positively held orv locked so that all of the power from theoperating device is carried direct to the brush.

`A further object of the invention is to provide a novel rotary brush,the body of which is made of a material that will not be affected by thewater, and which isso constructed that the same may freely pass from theinterior thereof to and through .the bristles to-ass'ist in the cleaningoperation. Furthermore, 4it is proposed to make the brush of such adesign thatit will readily t into the corners and more or less concealedplaces usually found on a vehicle.

YWith `the above and otherv objectsin view ywhich will more readilyappear as the na-.

In this connection, the

ture of the invention is better understood,

the same consists in the novel'construction,

combination and arrangement of parts here.

inafter more fully described, illustrated and claimed.

A preferred and practical embodiment of the present invention isillustrated in the accompanying drawings, in which.-

Similar reference characters designate;Y

corresponding parts throughout the several figures of the drawings.

A novel and distinctive feature of the present invention resides in theprovision of a suitable casing having at one' side an inlet connection,and an oppositely located outletl extension having'fitted thereto-arotatable brush. which is capable of distributing the water passingthrough the casing for the washing operation, after it has operated thebrush actuating mechanism.y r

-As will be observed from the several Inigures of the drawings, thiscasing is -designated generally as C, and essentially comprises thecomplemental sections 1 and 2 which may 'be secured together by suitablefastening elements 3. Referring to the novel features of constructionofthe casing,

it .will be noted .that the section 1 thereof is provided with an inletconnection 4, while the portion of the section directly opposite thisconnection is formed with an extended neck portion a which together witha correeoy sponding neck portion 'b of the complemental section 2providesan outlet extension f 5 having an open discharge -mouth 6. Itwill thus be apparent that 'water supplied to the casing through theinlet connection 4l will have a vsubstantially direct passage'throughithe same tol exhaust-through the discharge mouth 6. The saidoutlet extension 5- is provided with an annularflange 7 whichconstitutesan abutment for asuitable 'washer 8, that is intended to protect or.

shield the part of the vehicle being washed from being scratched ormarred by the metal casing, but at the same time has another functionwhich will hereinafter more-fully appear. The inlet connection 4 isinteriorly threaded as shown in Fig. 2, to detachably receive thethreaded end of a hollow'pipe 9 which constitutes a handle formanipulating the present device. This pipe 9 is provided at one end witha suitable coupling member 10 for connecting With a hose or otherconvenient source of water supply, and is provided at the opposite endwith internal threads for receiving the threaded shank 11 of a jetnozzle 12. As Will be clear from Fig. 2, this jet nozzle 12 is locatedWithin the inlet connection 4, and is adapted to direct a jet of Waterinto the interior of the casing C.

The water fed into the casing by means of the nozzle 12 is adapted toactuate a brush operating motor which is housed and concealed within thecasing. This motor essentially comprises a water wheel 13 having aplurality of cuppedimpact blades 14 which are disposed directly in thepath of discharge of the jet nozzle v12. The said wheel 13 is carried bya transmission shaft 15 having its opposite ends respectively journaledin the sections 1 and 2, and also carrying a worm 16. In connection withthe'end ofthe shaft journaled in the section 2 it will be observed thatthe same may be provided with a plurality of bearing washers w, and mayalso be supplied with lubricant from the tube T formed on the exteriorof the section by the adjustment of the vscrew S. This arrangement ofthe shaft 15 causes thesame to be' disposed transversely of the interiorofthe casing, and facilitates the meshing of the Worm 16 carried therebyWith a Worm pinion 17 mounted on a motor driven shaft 18. This shaft 18is carried in suitable brackets 19 formed from the inner side of thesection 2, and' is also provided with a shaft casing 20 which not onlyfacilitates the assembling of the device inasmuch as it holds the wormpinion 17 in position, but also protects the said shaft from rust andcorro-sion and provides a more substantial and steady bearing therefor.`It will also-be noted that this shaft is disposed longitudinally of thecasing, and therefore at right angles to the transmission shaft 15, andis located i'n the center of the outlet eX-v tension 5, and therefore inthe direct line' lof discharge' or passage of the water through thecasing.

The frontend of the motor shaft 18 is provided with a slot 21 forengaging with the locking plate 22 Whichvi's secured within thehollowconical body of the rotary brush designated inI its entirety bythe reference character B. This brush essentially comprises a yhollowperforated conical core 23,

License and is provided at its rear Vend with a suitable spider 24,which is rigidly secured toL issuing from the discharge mouth 6 thereofl flows into the interior of the core, and makes its way to the brushbristles through the plurality of perforations p therein. In thisconnection it `will also be noted that the spider 24 and locking p late22 are arranged Within the interior of the core so as to permit the rearend of the core to fit over the end of the extension 5 and abut againstthe washer 8 which maybe of leather, rubber,`

or any other suitable material, to thus protect the operator bypreventing water from splashing back over the casing C.

Referring to the additional features of construction involved inconnection with the brush B, particular reference may be made to Figs.4, 5 and 6. From these figures it will be observed that the hollow core23 is substantially frusto-conical. That is to say,

the upper end thereof is cut off to provide for receiving an end plug26, which may be made fast to the core by means of azsuitable fasteningelement 27 lfitting into the opening 27a. This end plug 26 is providedwith a discharge passage 28', and is also provided with a series ofspaced annular flanges 29 which gradually diminish in diameter and havetherebetween the grooves 30 lwhich are 4connected by means of an obliqueslit 31 in the flanges' 29. These grooves 30 are adapted to receive thebristles to form the ends of the brush, and correspond to the continuouschannel member 32 on the core. This channel member is spirally woundfrom one end of the core 23 to the other, and is preferably made oflight metal, as is also the core or brush body 23, thus making itpossible for sthe channel member to be soldered or otherwise secured tothe brush body, in a manner Which will not be affected by the water.

The bristles designated generally as 33 in thebrush B are held inposition by means of a retaining Wire 34. That is to say, a singlecontinuous retaining Wire having one end made fast tothe. core,preferably at its bottom end, is wound into the channel, thus pressingthe bristles laid across the same into such aJ positibn4 that they standoutwardly from the core body as shown in Fig. 5, and also in Fig. 2. Theplug 26 which is fitted in the end of the core or brush body, carriesits own bristlesinthel grooves 30 by a separate retainingl wire slmilarto the wire 34 which in practice has one end secured to the shank of theplug and then passes through each groove and to the adjoining one bymeans of the oblique slots 31. Thus, after 5 the core`23 is'fitted withits bristles, the'endl the Lsaid washer, and means within the casplugmay bel placed in position. V

From the foregoing, it will be apparent that water issuing from the jetnozzle 12 will strike against the cupped impact blades 14 of the waterwheel13, and thusturn `the worm pinion 17 on the shaft 18 will of coursebe rotated, thus turning the brush B through the means alreadydescribed.' Ac-V cordingly, it will be obvious that the'same water whichoperates the water wheel 13 passes on through the outlet extension 5 ofthe casing to the vbrush to 'be used in" the washing operation, thusutilizing the water for the two-fold purpose of operating the brush andassisting the same in the cleaning operation.

Without further description, it isv thought that the many features andadvantages of the present invention will be readily apparent, and itwill also be understood that "changes in the form, proportion, and minordetails of construction may be resorted to without departing from .the'spirit ofthe invention or scope of the appended claims.
